Thomas Mueller updated OAK-11712:
---------------------------------
Description:
:path cannot be used for searches, just for sorting: docValues is more than
enough. In some cases, this could decrease the space taken for this specific
field up to 50%.
>From the docs:
https://www.elastic.co/docs/reference/elasticsearch/mapping-reference/doc-values
"Doc-value-only fields: Numeric types, date types, the boolean type,... and the
keyword type can also be queried when they are not indexed but only have doc
values enabled. Query performance on doc values is much slower than on index
structures, but offers an interesting tradeoff between disk usage and query
performance for fields that are only rarely queried..."
